Purpose Development of a System Manager Application for Monitoring and Management of a Control and Data Acquisition System Hardware. 3

Control in Nuclear Fusion Plasmas is Critical for Safe Operation and to Achieve High Performance Magnetic control Position, Shape & Vertical Stabilization Wall Protection Malfunction of a single component may originate Critical Damage to entire infrastructure! Density Control Instabilities Mitigation & Control 4

Fusion Reactor (Tokamak) Why Monitoring? Fusion Reaction Diagnostics Nuclear Fusion Plasmas Behavior Study and Understanding. How? Acquisition and Feedback Control Answer: Control and Data Acquisition Instrumentation Plasma Shape, Positioning and Vertical Stabilization Demands Critical Realtime Tasks to Prevent Machine Components DAMAGE and Plasma Termination! Monitoring and Hardware Management to AVOID Instrumentation Failure! 5

Why ATCA and u. TCA Systems? Implementation and tests will take place on ATCA platform (Ref. 1) but can be used with other form factors such as u. TCA.

Communication Protocols Description • External Sys Manager • TCP/IP • IPMI Over LAN • Shelf Manager Controller • I 2 C (IPM Controller) • PCI Express • Hardware Access • Acquisition • Card Configuration Figure 13. ATCA External System Manager Software Architecture. 14

Software Design • External System Manager can use the HPI and IPMI platforms to query the Sh. MC for system information, status and sensor readings. • Waits for response from IPMCs to inform a control room operator about the system healthy status and notify in case of alarm occurences. • System log to store important realtime events ocurring in the system to provide later analysis and report capabilities.

Software Architecture Inter-layer connection is performed in a top-down perspective using the common standard communication protocols provided by the required instrumentation specifications. Figure 12. Software Architecture Internal Communication Protocols Block Diagram. 16

System Maintenance Continuous (Reduces Data Losses) Applications Proper Termination • Provided by Redundancy In Software Modules In Hardware Components AMC RTM Module • Damaged Hardware • Unit Replacement Required • HW Availablility Check • Provide System Operation AMC AMC ATCA-PTSW-AMC 4 Time Switch Board 17
